I To all whom it may concern:

Be it known that I, DANIEL T. GLAoKIN, a citizen of the United States,residing in Chicago, in the county of-ook and State of Illinois, haveinvented certain new and useful Improvements in Type-Writing Machines,of which .the following'is a speci:

carbon sheets are carried by arms, and these arms extend into the opensides of the longitudinal web folds. The carbon sheets are advancedintermittently to successive fresh portions of the web. The web isusually perforated at the fold, so that a part thereof may be severedwhen desired. To prevent the web from being damaged by the free end ofthe carbon-carrying arm, a straightener is provided on said end, whichengages and straightens out'any irregularities that may exist in the.folded portions of the web, when the carbon sheets are beingrepositioned.

It is sometimes the practice to provide the web withmarginal'perfo'rations, so that the severed sheets may be used inloose-leaf binders. This perforating, however, causes the folded-overportion or leaf of the web to be uneven" and irregular; so much so, thatit is liable to become damaged by reason of the perforations catching onto the carbon-carrying arm that is arranged above or below theperforated part, when said carbon-carryin% arm 'is being moved along theweb.

0 prevent the web from being thus caught and damaged, the presentinvention provides a deflector. connected to the carboncarrying arni.The deflector extends rearwardly, so as to be in advance ofthecarboncarrying arm during the shlftingof the I latter along the web,and has a rounded and thinned or beveled deflecting portion whichengages the web beyond the erforated margin. The deflector gradua 1yrises or mcreasesin thickness toward its base or mount' onthe'carbon-carrym arm, and thus forms a slope which deflects t e'weboverand away from the carbon-carrying arm as the carbons are beingrepositioned.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure lris a perspective view of a portion of a fan-fold machine,showing my invention applied thereto.

Fig. 2 is also a perspective view, showing the carbon holding arm with aweb straightener at one end of the carbon-carrying arm, and also mydeflector at the other end of said carbon-carrying arm.

Fig. 3 is a top plan view of a portion of a carbon-carrying arm, showinthe-manner in which the webs having per orations at the sides, aredeflected over the carbon-carrying arm.

Types 1O strike upwardly and rearwardly against the front of a platen 11to make impressions on a fan-folded work-sheet 12, between the folds ofwhich are arranged. carbon sheets 13. Each of the carbonsheets 13 isattached to. a reciprocating carriage 14,

which is drawn forwardly upon its frame 15 by the movement of theplaten, as the sheets pass around the same in line-space direction. 7 I

The carbon sheets are attached to the carriage 14 by means ofblade-like-bars or arms 16, which are removably attached to thereciprocating carriage by pins 16 which extend into holes in the frameof the carriage 14.: Each of the carbon sheets 13 is held to its arm 16by being wrapped around a blade 17 and then secured by means of a clamp17 pivoted to the carbon-carrying blade 17.

, The fan-fold web 12-is usually provided with lines of perforations 18at its folds, so that the several parts thereof may be easily separatedafter 'a form has been written upon anddetached.

- After the writing of a form has been completed, the carbon sheets 13are. repositioned or advanced to a fresh portion ofthe web, by movingthe carbon-carriage 14 with its carbon-carrying arms 16 rearwardly.

To prevent the web from liability of being damaged by the .free end ofthe carbon-carrying arms 16, as the arms are moved to new positions, thefree end of each arm 16 is provided with a straightener 19 in the formof a flat sheet-metal plate extending rearwardly from said arm, andhaving its outer edge 20 inclined inwardly and rearwardly from the endof the arm, so that said end 20 will gradually engage and straightenthe. web before the irregular portion can reach the abrupt edge of thecarbon-carrying arm 16.

When using fan-fold webs having binding perforations at some of theirfolded portions, it has been found, that the web thus" made uneven orirregular, is liable to become damaged by the carbon-carrying arm 16, asexplained. A deflector 21 is therefore provided on each carbon-carryingarm 16. This deflector 21 is arranged at the inneror fixed side of thecarbon-carrying arm 16, and may be mounted directly upon the pivotedclamp 17. The deflector or guide 21 extends rearwardly from thecarbon-carrying arm, and is rounded and thinned at its rearwardextremity 22, and has a sloping portion 25 which safely guides any ofthe corners 23 or other irregularities formed on the web 12 by theperforations 24 over the carbon-carrying arm 16.

It will be noted that the deflector 21, being mounted on the inner orfixed side of the carbon-carrying arm 16, comes in contact with twofolded portions of the web, one above and the other below. The guide 21is therefore provided with two sloping portions 25, one for guidingthe'upper portion of theweb over the top of the carbon-carrying arm 16,and the other for guiding the lower portion of the web under saidcarboncarrying arm. The guide 21 in this way prevents either the upperweb or the lower web from fouling on the abrupt edge of thecarbon-carrying arm.

The thinned extremity 22 of the guide 21 extends into the fold of theweb beyond the depth of the perforations, so that the web is firstengaged at a portion where it is continuous, and is then graduallylifted as the perforated portion 24 engages the guide. These perforatedportions are thus lifted up on the sloping surface 25 of the guide 21,by the engagement of the web with the advance extremity 22.

i The guide 21 is arranged at the inner or fixed end, and thestraightener 19 is arranged upon the outer or free end of thecarbon-carrying arm 16, and that both the deflector 21 and thestraightener 19 maybe used advantageously on the same arm.

The clamp 17*, which is made of springy material, may be held to thecarbon-carrying blade 17 by means of the depression 26 on sald clamp,which engages with an opening 27 in the carbon-carrying blade 17 Thestraightener 19 may be removably held upon theclamp or spring fingers28,

memes which have portions 29 adapted to frictionally hold thestraightener 19 to the clamp.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.

Having thus described my invention, I claim:

In a typewritingmachine, the combination of an arm supported at oneend to carry a carbon sheet, said arm extending into the fold of afan-folded web, a straightener on .the outer end of said arm-to preparethe web at its folded portion for the advance of the carbon-carrying armto a new portion of the web, and a deflector for the inner end of saidcarbon-carrying arm, to engage the outer portion of a perforated webfold and guide the -same over the carbon-carrying arm, without liabilityof fouling.

2. In a typewriting machine, the combination with a reciprocatingcarbon-retracting carriage, of arms connected at one end to saidcarbon-retracting carriage to which carbon sheets are attached, saidarms extending between the folds of a fan-folded web, and a guide forthe inner orfixed end of. said carbon-carrying arm for engaging theoutside of the fan-folded web and guide the same over thecarbon-carrying arm.
